Description
Technical Field
The invention relates to the field of full-automatic blood analyzers, in particular to an ultrasonic cleaning control circuit for a blood analyzer.
Background
The blood analyzer is a common tool in a laboratory and is also a basic clinical examination tool, and in the using process of the instrument, the cleaning work is a very important work in the maintenance of the instrument, and whether the cleaning is correct and thorough directly influences the accuracy of a test result and the service life of the instrument.
The internal cleaning of the blood analyzer in the market can be divided into the following cleaning processes:
1) And (4) performing a backflushing program to perform backflushing, wherein when the counting hole is blocked by the instrument, the counting hole can be cleaned by the operation.
2) An evacuation process is performed, which checks whether the liquid in the apparatus is properly evacuated.
3) And performing the irrigation program, operating the required irrigation program, and irrigating all programs. In addition, after a certain number of samples are made, the WBC and RBC counting cells are concentrated and cleaned.
From the evolution of blood analyzers, initial instrument cleaning relied on manual soaking or cleaning with a brush. If a very high value specimen is tested, it needs to be washed with a blank solution to prevent carrying contamination of the next specimen. After a sample is detected by a plurality of analyzers, the small counting holes and the pipelines can be automatically washed, and the inside and the outside of a sampler, a diluter and a sampling needle can be comprehensively cleaned at the same time, so that the chance of cross contamination is reduced; when some instruments are started and shut down, the cleaning program can be automatically executed or the cleaning program can be regularly cleaned according to the preset cleaning program, so that the normal work of the instruments is ensured. However, the cleaning is usually simple and temporary, the cleaning is usually short in time and weak in force, the effect to be achieved is only the washing effect, trace or even small amount of impurities or dirt are inevitably attached to the tube wall, and the possibility of polluting the reagent is higher and higher as the time is longer and the more the impurities or dirt are attached, and the accuracy of the test is even affected. Therefore, the instrument needs to be cleaned in an omnibearing, deep and thorough way when needed, and the ultrasonic cleaning can achieve the effect.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Referring to fig. 1, an ultrasonic cleaning control circuit for a blood analyzer includes; the input terminal J1, a pin 1 of the input terminal J1 is grounded, a pin 2 receives and outputs a control signal, and a pin 3 receives and outputs 5V voltage; a pin 1 of the triode Q1 is connected with the control signal through a resistor R2, the pin 2 is grounded, and a pin 3 is connected with the 5V voltage through a resistor R3; the pin 1-3 of the control chip U1 is grounded, and the pin 4 is connected with the pin 3 of the triode Q1; and the output terminal J2 is used for being connected with an ultrasonic motor, a pin 1 of the output terminal J2 is connected with the 5V voltage, a pin 2 of the output terminal J2 is connected with pins 5-8 of the control chip U1 in a sharing mode, the 5V voltage is further connected with a pin 2 of the output terminal J2 through a resistor R1, and preferably, the resistor R1 is further connected with a light emitting diode D6.
Preferably, the model of the control chip U1 is IRF8788 TRBF.
Preferably, the type of the light emitting diode D6 is LED0603G.
It should be noted that an ultrasonic wave is a sound wave having a frequency exceeding the human auditory range (20 kHz) and the ultrasonic wave propagates through an elastic medium, and when propagating, the ultrasonic wave oscillates particles in the elastic medium and transmits energy through the medium in the propagation direction of the ultrasonic wave, and the ultrasonic wave is divided into a longitudinal wave and a transverse wave. Within a solid, both longitudinal and transverse waves can be transmitted; whereas in gases and liquids only longitudinal waves can be transmitted. Ultrasonic waves can cause particle vibrations whose acceleration is proportional to the square of the ultrasonic frequency, so that ultrasound with a frequency of tens of kilohertz produces significant forces. During ultrasonic cleaning, a high-frequency oscillation signal emitted by an ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and is transmitted into a medium, namely a cleaning solvent, and ultrasonic waves are radiated forwards in the same density in the cleaning liquid to make the liquid flow to generate tens of thousands of micro bubbles. These bubbles form and grow in the negative pressure region where the ultrasonic waves propagate longitudinally, and close rapidly in the positive pressure region, which is called the "cavitation" effect. The bubbles are closed when the cavitation effect is generated, so that instant high pressure exceeding 1000 atmospheric pressure can be formed, and the instant high pressure is continuously generated like a series of small explosions to continuously impact the surface of the object, so that dirt on the surface of the object and in gaps is rapidly peeled off, and the purpose of purifying the surface of the object is achieved.
The application utilizes the principle to realize cleaning by matching with the schematic circuit structure diagram shown in figure 1, and the principle is as follows:
the ultrasonic cleaning system consists of three parts, namely a control panel, an ultrasonic motor and an energy-converting vibration arm, wherein the control panel provides on-off electric energy with certain frequency for the ultrasonic motor, so that the ultrasonic motor vibrates according to the set frequency to generate an ultrasonic vibration signal; the vibration signal generated by the ultrasonic motor is transmitted to the cleaning liquid through the transduction vibration arm connected to the rotating shaft of the motor, and a 'cavitation' effect is formed in the cleaning liquid, so that the purpose of purifying the surface of an object is achieved.
Wherein, 5V voltage is provided by an external power supply to supply power for the control board and the ultrasonic motor;
the CLEAR _ CONTROL is a CONTROL signal with a certain frequency, and the CONTROL signal CONTROLs the on-off of the triode Q1 through a resistor R2; and the on and off of the Q1 controls the on and off of the U1, thereby controlling whether the ultrasonic motor is powered or not. When Q1 is disconnected, U1 is connected, and 5V voltage supplies power to the ultrasonic motor; when Q1 is switched on, U1 is switched off, and 5V voltage stops supplying power to the ultrasonic motor. The CLEAR _ CONTROL CONTROL signal with a certain frequency enables Q1 to keep on and off with the same frequency, so that U1 is controlled to keep off and on with the same frequency, 5V power supply voltage applied to the ultrasonic motor also keeps off and on with the same frequency, and therefore ultrasonic signals with the same frequency are generated on the rotating shaft of the ultrasonic motor. D6 is power supply state indication of the ultrasonic motor, R1 is a D6 current-limiting resistor, so that the current flowing through D6 is in a specified range, the D6 is protected from being damaged, and when the ultrasonic motor supplies power, the D6 is lightened; when the ultrasonic motor is powered off, D6 is extinguished.
In order to ensure the optimal ultrasonic cleaning effect, the frequency and duty ratio of the CLEAR _ CONTROL signal need to be reasonably set, so that the ultrasonic motor controlled by the CLEAR _ CONTROL signal vibrates in an optimal state.
The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not intended to limit the scope of the present application, which is within the scope of the present application, except that the same or similar principles and basic structures as the present application may be used.
